Sketch aided route selection for navigation devices and applications

ABSTRACT

One particular example includes a system, comprising a processor and a memory to store instructions that when executed by the processor performs operations, comprising displaying a map of a first area on a display; receiving an instruction to designate a second area on the map to be avoided; displaying the second area to be avoided on the map; and generating a route from a first point to a second point, where the route does not go through the second area to be avoided.

TECHNICAL FIELD

Examples described herein generally relate to sketch aided route selection for navigation devices and applications.

BACKGROUND

Navigation systems, electronic maps (also known as digital maps), and geographical positioning devices are increasingly used by travelers to assist with various navigation functions, such as to find destinations and addresses, calculate optimal routes, and provide real-time driving guidance. Typically, the navigation system includes a small display screen or graphic user interface that portrays a network of roads and a general visual display of an area. To find a route to a specific place or address, typically a user will enter the specific place or address and the navigation system will calculate a route to the specific place or address. Then the navigation system will plan a route based on the software used by the navigation system. However, sometimes a user may not want the route to pass through a certain area or may want the route to go through a certain area. Also, a user may have information about an area that the navigation system does not have, such as a new construction area. It would be beneficial if the user could designate areas to be avoided and/or areas that are preferred.

DETAILED DESCRIPTION

The following detailed description sets forth examples of apparatuses, methods, and systems relating to single touch or dual touch surface multiple function input devices. Features, such as structure(s), function(s), and/or characteristic(s) for example, are described with reference to one example as a matter of convenience; various examples may be implemented with any suitable one or more described features.

FIG. 1A is a simplified diagram illustrating an example of a navigation device 10. Navigation device 10 can include a display 12, a processor 14, a memory 16, and a route selection module 18. The example illustration of FIG. 1A is merely representing one (of the many) possible configurations of an electronic configuration. For example, the number of electrical components may vary, the placement of the electrical components may vary, and/or the like.

Display 12 can be configured to offer a screen on which navigation data can be rendered for a user. Note that as used herein in this Specification, the term ‘display’ is meant to connote any element that is capable of displaying a digital map of an area to the user. This would necessarily be inclusive of any panel, plasma element, television (which may be high-definition), monitor, computer interface, screen, projector, Telepresence devices (inclusive of Telepresence boards, panels, screens, surfaces, etc.), touch screens, or any other suitable element that is capable of delivering/rendering/projecting such information. Processor 14 can include one or more processing cores and one or more graphics cores.

Processor 14 can execute any type of instructions associated with the data to achieve the operations detailed herein in this Specification. In one example, processor 14 could transform an element or an article (e.g., data) from one state or thing to another state or thing, in another example, the activities outlined herein may be implemented with fixed logic or programmable logic (e.g., software/computer instructions executed by the processor) and the elements identified herein could be some type of a programmable processor, programmable digital logic (e.g., a field programmable gate array [FPGA], an erasable programmable read only memory (EPROM), an electrically erasable programmable ROM (EEPROM)) or an ASIC that can include digital logic, software, code, electronic instructions, or any suitable combination thereof. Route selection module 18 can be configured to receive input regarding areas on a map (shown on display 12) that are to be avoided, are preferred, are acceptable, etc. It could also receive input as to designating a particular a route (or an interim route) through which the pathway should traverse on the way to the destination.

User interfaces in navigation devices and applications are cumbersome to use when selecting a route based on being given a starting and ending point on a map. In addition, in many scenarios, the navigation system selects a best route from a route optimization perspective, which is only a few minutes better than the route that the user would prefer for personal preferences or based on knowledge that the navigation system does not have. However, interacting with modern navigation systems and providing the correct input, information, and desires that allows for personal preferences or knowledge that the navigation system does not have is challenging. Further, particular touch capabilities of modern navigation systems are not fully exploited.

In an example, navigation device 10 can be configured to allow a user to approximately sketch or draw a desired (or undesired) route on display 12. The sketched route can basically give a hint to the system for which route the user prefers (or does not prefer). For example, using symbols and/or colors, areas on the map can be marked as areas to be avoided or areas that are preferred. The symbols and/or colors may include various shapes, color-coded, or some other type of representation that can distinguish one area from another area, or they can be automatically assigned or set by the user as personal preferences. The sketching activity can be performed by the user to approximately indicate the route on the map regardless of the zoom level selected. In an example, navigation device 10 can be configured to allow the user to either select a preferred route, areas that are okay to consider during planning but not preferred, or sections to be avoided.

More specifically, when planning a route, route selection module 18 may take a sketched route and areas that are preferred or to be avoided into consideration and try to accommodate the user's requests. For example, a heuristic-based approach may be utilized to compare the possible routes with the user identified areas or routes that are preferred or are to be avoided. If a route to a destination crosses an area that is to be avoided, that route may be discarded. In a case where all the routes travel through an area to be avoided, the route with the least amount of overlap in the area to be avoided may be proposed to the user first. In an example, a function may be used to penalize routes that are closer to the undesirable area and distant from a desired area.

In another example, a penalty or weight factor may be assigned to each point on a map, depending on the type of area or vicinity of the route at which the point is located (that would be computationally expensive). As an alternative, voronoi diagrams may be used, where a penalty or weight factor is assigned to each voronoi polygon according to its overlap with an area that is to be avoided and/or an area that is preferred or acceptable. Voronoi diagrams are commonly used in spatial systems to perform space decomposition and spatial queries. To have a measure of how close a computer route is to a user sketched route, an algorithm such as dynamic time warping (DTW) may be utilized to compare the two routes. DTW is commonly used in time series, such as handwriting, to compare two time-varying and/or space-varying signals.

FIG. 1B is a simplified diagram illustrating an example of navigation device 10. As illustrated in FIG. 1B, an avoid area symbol 20 has been drawn in one area, an acceptable area symbol 22 has been drawn in another area, and a preferred area symbol 24 has been drawn in yet another area. Avoid area symbol 20, acceptable area symbol 22, and preferred area symbol 24 are merely representations, as they reflect any symbol the user may use to designate an area. For example, while acceptable area symbol 22 is shown having a “v” profile, a check mark, the word “OK”, or some other symbol may be used to designate the area as an acceptable area. Appropriate algorithms, such as DTW, Hidden Markov Model (HMM), or other methods can be used to recognize the symbol being drawn. For example, the user can select (or draw) the symbol(s) during a training phase and put those symbols in a dictionary. An algorithm, at runtime, can detect the most similar symbol in the dictionary and attach a label accordingly the surrounding area that is comprised in the closed convex shape drawn by the user.

Avoid area symbol 20 indicates an area that the user does not want the route pass through. For example, the area covered by avoid area symbol 20 may have heavy construction or may be particularly busy at a certain time of day or experience very dynamic or unpredictable conditions. Acceptable area symbol 22 indicates an area that is acceptable for the route to pass through. For example, the area covered by acceptable area symbol 22 may be an area that the user would not mind if the route passed through the area. Preferred are symbol 24 indicates a preferred area for the route to pass through. For example, the area covered by preferred area symbol 24 may be scenic, have well-maintained roads, smooth roads, typically not have very much traffic, etc. The term “road” is used to encompass a street, highway, interstate, or any other thoroughfare, route, or way between two places, which has been paved or otherwise improved to allow travel.

FIG. 1C is a simplified diagram illustrating an example of navigation device 10. As illustrated in FIG. 1C, route selection module 18 has generated route 26 a. Route 26 a is mostly within the area around preferred area symbol 24 and a small portion of generated route 26 a extends into the acceptable area designated with acceptable are symbol 22. Route 26 a does not extend into the area around avoid area symbol 20.

FIG. 2A is a simplified diagram illustrating an example of navigation device 10. As illustrated in FIG. 2A, a relatively large and not very detailed map is displayed on display 12. The relatively large map may be used when it is desired that the route go through a general area. For example, if the route was to start in Alexandria, Va. and the destination was someplace in Mississippi, then a preferred area symbol 24 could be drawn between the start and destination point. If it was preferable for the route to pass through the state of Tennessee, then preferred area symbol 24 could be drawn to include Tennessee, as shown. If for some reason it was preferable for the route to not pass through Georgia, then avoid area symbol 20 could be drawn around Georgia. A zoom out selector 28 may be used to increase area shown on display 12. A zoom in selector 26 may be used to decrease the area shown on display 12.

In another example, shown in FIG. 2B, if the route was to start in Raleigh, N.C. and the destination was Alexandria, Va., and it did not really matter the route taken (e.g., there are no areas to avoid), then a preferred area symbol 24 could be drawn between the start and destination point. Because preferred area symbol 24 was drawn on a relatively large and not very detailed map, as illustrated in FIG. 2C, a route 26 b generated by route selection module 18 may be displayed on display 12. If more control over the route is desired, then zoom in selector 26 may be used to zoom on the map, as shown in FIG. 2D.

FIG. 2D is a simplified diagram illustrating an example of navigation device 10. As illustrated in FIG. 2D, a more detailed map than shown in FIG. 2B is displayed on display 12. The map may be used when it is desired that the route go through a specific general area. For example, if the route was to start in Raleigh, N.C. and the destination was Alexandria, Va., and it was desirable for the route to go through a bay area that is close to Richmond, Va. and off of Interstate 95, then avoid area symbol 20 could be drawn to include the area around Interstate 95 that should be avoided and preferred area symbol 24 could be drawn between the start and destination point and could include the desired bay area. Because avoid area symbol 20 was drawn to include the area around Interstate 95 that should be avoided and preferred area symbol 24 was drawn that included the bay area that is preferred, as illustrated in FIG. 2E, a route 26 c may be generated by route selection module 18 that includes the bay area but not Interstate 95 and the route can be displayed on display 12. If more control over the route is desired, then zoom in selector 26 may be used to zoom on the map, as shown in FIG. 2F.

FIG. 2F is a simplified diagram illustrating an example of navigation device 10. As illustrated in FIG. 2F, a more detailed map than shown in FIG. 2D is displayed on display 12. The map may be used when it is desired that the route go through a specific area or use a specific road. For example, a desirable route may include a specific road, (e.g., Highway 5 outside of Richmond, Va.) and/or a specific area (e.g., an area that is west of Williamsburg, Va.). If such a route is desired, then preferred area symbol 24 may be used to designate the preferred area. A specific road symbol 30 may be used to designate the preferred road. Avoid area symbol 20 may be used to designate areas the route should not pass through. Because preferred area symbol 24 was drawn that included the area west of Williamsburg and specific road symbol 30 was drawn on (or close to Highway 5), as illustrated in FIG. 2G, a route 26 d may be generated by route selection module 18 that includes Highway 5 and goes through an area that is west of Williamsburg and the route can be displayed on display 12.

FIG. 3 is a simplified diagram illustrating an example of navigation device 10. As illustrated in FIG. 3, color instead of a symbol may be used to designate areas on the map shown on display 12. For example, area select menu 32 may be used to designate an area. More specifically, an area to avoid may be designated with the color red. By selecting a red box in area election menu 32 and then selecting the area to avoid on the map shown on display 12, an avoid area 34 indication can be used to designate an area to avoid. Similarly, the color green can be used to designate a preferred area as illustrated by a preferred area 36 and the color yellow can be used to designate an acceptable area as illustrated by an acceptable area 38. The colors used to designate the area(s) to avoid, acceptable area(s), and preferred area(s) are merely representations and may be any color the user may use to designate an area. For example, while acceptable area is shown as being the color yellow, the color orange, purple, pink, or some other color may be used to designate the area as an acceptable area.

FIG. 4 is a simplified diagram illustrating an example of navigation device 10. As illustrated in FIG. 4, a voronoi type diagram having voronoi cells 54 a-l (or some other representation that can be assigned a penalty or weight factor) can be used. For example, voronoi polygons 54 h-l may have a high penalty factor and/or low or negative weight factor because they are in or include at least a portion of the area covered by avoid area indicator 40.

An acceptable area indicator 44 may not have any penalty factor, a low penalty factor, or a relatively low weight factor. A preferred area indicator 42 may not have any penalty factor and a relatively high weight factor or one that is higher than acceptable area 44. A preferred road indicator 48 may not have any penalty factor and a relatively high weight factor or one that is higher than preferred area 42. Using the penalty or weight factors, an algorithm (or some other analysis) may be used to determine a preferred route. Areas not covered by an indicator may not have any penalty factor or weight value assigned and may be considered neutral.

FIG. 5 is a simplified flowchart 500 illustrating example activities of a sketch aided route selection system. At 502, a map of an area is displayed. At 504, the system determines if there is a specific area on the map that should be avoided. If there is a specific area on the map that should be avoided, then an avoid area symbol and/or an avoid area color is displayed in the area that should be avoided, as in 506. For example, a user may draw or place a symbol or color around an area that should be avoided and the symbol or color will be displayed on the map in the area that should be avoided. If there is not a specific area on the map that should be avoided, then the system determines if there is a specific area on the map that is more acceptable than other areas on the map, as in 508.

If there is a specific area on the map that is more acceptable than other areas on the map, then an acceptable area symbol and/or an acceptable area color is displayed in the area that is more acceptable than other areas on the map, as in 510. For example, a user may draw or place a symbol or color around an area that is more acceptable than other areas on the map and the symbol or color will be displayed on the map in the area that is more acceptable than other areas on the map. If there is not a specific area on the map that is more acceptable than other areas on the map, then the system determines if there is a specific area on the map that is preferred, as in 512.

If there is an area on the map that is preferred, then a preferred area symbol and/or a preferred area color is displayed in the area that is preferred, as in 514. For example, a user may draw or place a symbol or color around an area that is preferred and the symbol or color will be displayed on the map in the area that is preferred. If there is not a specific area on the map that is preferred, then the system determines if there is a specific road on the map that is preferred, as in 516.

If there is a specific road on the map that is preferred, then a specific road symbol and/or a specific road color is displayed in the road that is preferred, as in 520. For example, a user may draw or place a symbol or color on a road that is preferred and the symbol or color will be displayed on the map in the road that is preferred. if there is not a specific road on the map that is preferred, then one or more routes are generated based on the symbols and/or colors (if any) on the map, as in 522. It should be understood that the “level” of preference might not be constrained to preferred/neutral/avoid but can include any scale of preference (e.g., areas could be assigned a number from one to ten). Also, any input method that enables the super imposition of a map and user defined areas or any other method that would facilitate the functionalities described herein are included in the spirit of this application.

FIG. 6 is a simplified block diagram associated with an example ecosystem SOC 600 of the present disclosure.

In at least one example, power management controller 718 is configured to reduce the power consumption of components or devices of system 700 that may either be operated at reduced power or turned off when the electronic device is in a closed configuration. For example, in at least one example, when the electronic device is in a closed configuration, power management controller 718 performs one or more of the following: power down the unused portion of the display and/or any backlight associated therewith; allow one or more of processor(s) 704 to go to a lower power state if less computing power is required in the closed configuration; and shutdown any devices and/or components that are unused when an electronic device is in the closed configuration.

Communications interface(s) 716 may provide an interface for system 700 to communicate over one or more networks and/or with any other suitable device. Communications interface(s) 716 may include any suitable hardware and/or firmware. Communications interface(s) 716, in at least one example, may include, for example, a network adapter, a wireless network adapter, a telephone modern, and/or a wireless modem.

System control logic 706, in at least one example, can include one or more I/O controllers to provide an interface to any suitable input/output device(s) such as, for example, an audio device to help convert sound into corresponding digital signals and/or to help convert digital signals into corresponding sound, a camera, a camcorder, a printer, and/or a scanner.

For at least one example, at least one processor 704 may be packaged together with logic for one or more controllers of system control logic 706.

For touch control, touch controller 702 may include touch sensor interface circuitry 722 and touch control logic 724. Touch sensor interface circuitry 722 may be coupled to detect touch input over a first touch surface layer and a second touch surface layer of a display (i.e., display device 710). Touch sensor interface circuitry 722 may include any suitable circuitry that may depend, for example, at least in part on the touch-sensitive technology used for a touch input device. Touch sensor interface circuitry 722, in one example, may support any suitable multi-touch technology. Touch sensor interface circuitry 722, in at least one example, can include any suitable circuitry to convert analog signals corresponding to a first touch surface layer and a second surface layer into any suitable digital touch input data. Suitable digital touch input data, for at least one example, may include, for example, touch location or coordinate data.

Touch control logic 724 may be coupled to help control touch sensor interface circuitry 722 in any suitable manner to detect touch input over a first touch surface layer and a second touch surface layer. Touch control logic 724, for at least one example, may also be coupled to output in any suitable manner digital touch input data corresponding to touch input detected by touch sensor interface circuitry 722. Touch control logic 724 may be implemented using any suitable logic, including any suitable hardware, firmware, and/or software logic (e.g., non-transitory tangible media), that may depend, for example, at least in part on the circuitry used for touch sensor interface circuitry 722. Touch control logic 724, for at least one example, may support any suitable multi-touch technology.

Touch control logic 724 may be coupled to output digital touch input data to system control logic 706 and/or at least one processor 704 for processing. At least one processor 704, for at least one example, may execute any suitable software to process digital touch input data output from touch control logic 724. Suitable software may include, for example, any suitable driver software and/or any suitable application software. As illustrated in FIG. 7, system memory 708 may store suitable software 726 and/or non-volatile memory and/or storage device(s).

Note that in some example implementations, the functions outlined herein may be implemented in conjunction with logic that is encoded in one or more tangible, non-transitory media (e.g., embedded logic provided in an application-specific integrated circuit (ASIC), in digital signal processor (DSP) instructions, software [potentially inclusive of object code and source code] to be executed by a processor, or other similar machine, etc.). In some of these instances, memory elements can store data used for the operations described herein. This can include the memory elements being able to store software, logic, code, or processor instructions that are executed to carry out the activities described herein. A processor can execute any type of instructions associated with the data to achieve the operations detailed herein. In one example, the processors could transform an element or an article (e.g., data) from one state or thing to another state or thing. In another example, the activities outlined herein may be implemented with fixed logic or programmable logic (e.g., software/computer instructions executed by a processor) and the elements identified herein could be some type of a programmable processor, programmable digital logic (e.g., a field programmable gate array (FPGA), a DSP, an erasable programmable read only memory (EPROM), electrically erasable programmable read-only memory (EEPROM)) or an ASIC that can include digital logic, software, code, electronic instructions, or any suitable combination thereof.

Note that with the examples provided above, as well as numerous other examples provided herein, interaction may be described in terms of layers, protocols, interfaces, spaces, and environments more generally. However, this has been done for purposes of clarity and example only. In certain cases, it may be easier to describe one or more of the functionalities of a given set of flows by only referencing a limited number of components. It should be appreciated that the architectures discussed herein (and its teachings) are readily scalable and can accommodate a large number of components, as well as more complicated/sophisticated arrangements and configurations. Accordingly, the examples provided should not limit the scope or inhibit the broad teachings of the present disclosure, as potentially applied to a myriad of other architectures.

It is also important to note that the blocks in the flow diagrams illustrate only some of the possible signaling scenarios and patterns that may be executed by, or within, the circuits discussed herein. Some of these blocks may be deleted or removed where appropriate, or these steps may be modified or changed considerably without departing from the scope of teachings provided herein. In addition, a number of these operations have been described as being executed concurrently with, or in parallel to, one or more additional operations. However, the timing of these operations may be altered considerably. The preceding operational flows have been offered for purposes of example and discussion. Substantial flexibility is provided by the present disclosure in that any suitable arrangements, chronologies, configurations, and timing mechanisms may be provided without departing from the teachings provided herein.

It is also imperative to note that all of the Specifications, protocols, and relationships outlined herein (e.g., specific commands, timing intervals, supporting ancillary components, etc.) have only been offered for purposes of example and teaching only. Each of these data may be varied considerably without departing from the spirit of the present disclosure, or the scope of the appended claims.
